SELF-SETTING ANNUNClATOR-INDICATOR.

SPECIFICATION forming part of Letters Patent N o. 620,998, dated March 14, 1899.

Application filed March 20, 1 8 9 7.

To @ZZ whom t may concern.-

Be it known that I, FRANcIs CUYLER VAN DYCK, J r., a citizen of the United States, residing at New Brunswick, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in Self-Setting Annunciator-Indicators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention is an improvement in annunciators, and has for its object to construct an annunciator in which only one :indicator shall appear at one time and in which the act of completing a secondv call shall return the previously-actuated indicator to its place.

In the accompanying drawings I have illustrated one form in which I have contemplated embodying my invention, and the said invention is fully disclosed in the following description and claims.

In the drawings, Figure 1 is a vertical lsection from front to rear of a simple form of my improved annunciator. Fig. 2 is a sectional view taken at right angles to that of Fig. 1.

In the gures is represented an annunciator-box A, with six indicator-plates a a2 a3 c4 d5 a6. Each of these is attached to a lever b,Y which is provided with an armature b in the proper position to be actuated by an electromagnet B when the latter is energized and lift the lever, with its index or indicator plate. Each lever is provided with a retaining-hook c, which is provided with the inclined face c', to engage and move out of its path the swinging retaining-bar C. This bar has an inclined face to be engaged by the hooks c, and extend'- ing the whole length of the box is supported at each end by arms c2, pivoted at c3 `to the sides of the boX. These arms are preferably provided with angularly-extending arms d', which are pivoted to a link D,` by which theY two swinging bars C are operatively connected for joint action, so that when one is moved the other is given a like movement.

In the drawings one of the indicator-plates a2 is shown as having been drawn upward by its actuating-magnet and is in position before an opening A in the casing, in which position Serial No. 628,469. (No model.)

'released It will be seen that the movement of the upper bar C in such case is participated by thellower bar, and if there had been any lever Zi and its indicator-plate held by either bar such lever and bar would have been released and would have fallen to its normal inactive position. It will also be seen that should any other magnet and lever be actuated such action would release plate a2, which would return to its original position.

The invention here described is substantially the same as that shown, described, and claimed in my former application, led April 4, V1890, Serial No. 346,631, which became abandoned, and this application is filed as a substitute'for said earlier case.

The electric connections of the magnets B are not shown,as such are old and well known, andthe magnet B is also joined with a callbell in the manner usual in such cases.

While I have shown and described my invention only as applied to annunciators having indicator-plates, I propose to apply them to other forms of annunciators having indicators of different characters.

What I claim, and desire to secure by Let- 1. In an annunciator the combination with a horizontal series of vertically-movable indicators, each provided with a hook having a beveled face, of a transversely-disposed swinging retaining-rod for all of said hooks provided with a beveled face, a second horizontal series of annunciators in a different horizontal plane from the rst series provided with similar hooks, a similar transverse retaining-bar for said hooks, and operative connections between said transverse retainingbars for insuring their simultaneous movement, substantially as described.

2. In an annunciator, the combination with a horizontal series of electromagnets, a series of indicator-carrying rods each provided with an armature adjacent to one of said magnets, and carrying an indicator at its outer end and a hook on each of said rods extending up- IOO Wardly therefrom, and provided with a beveled face, of a horizontal swinging retainingbar extending transversely of said hooks, and provided with a beveled face adapted to be engaged by the beveled faces of the same, whereby each of said magnets in raising its indicator-rod and indicator will cause its hook to engage the retaining-bar and move it to disengage the hook of any other indicatorrod which may be held in elevated position 1o by said retaining-bar, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
